Zusammenfassung:The second harmonic coefficient d33 values of a series of polyester nonlinear optical (NLO) polymers, differing in their electron withdrawing substituent, were experimentally measured. The observed order of contribution of the substituents towards d33 value was rationalized by a frequency factor dependence. Excellent photostability and the highest d33 value among the series have been found for the polyester with 2,4-dinitro substituents in the side chain. A possible influence of intermolecular interaction is also indicated.
